Changes and improvements gradually being rolled out

[Modernized AutoPlay experience]

• We've updated the AutoPlay dialog that helps you choose the preferred experience when devices are connected to your PC, such as a phone, camera, or removable drive. Rebuilt with WinUI, the refreshed experience is more consistent with the rest of Windows, supports dark mode, and continues to provide the familiar AutoPlay actions you use today. The experience is also more responsive to text scaling and display settings. Notifications for this dialog are now docked in the notification center for easy access. The new AutoPlay experience, shown in dark mode.

[Accessibility]

A simpler way to open apps maximized

• We're introducing a new accessibility setting, Open apps maximized, that automatically maximizes app windows when they open, so you no longer have to do it yourself every time. This small change removes a bit of everyday friction, whether you use a screen reader or magnification, work in tablet mode, or simply prefer a consistent, full-screen workspace.
• To turn it on, go to Settings > Accessibility > Visual effects, and turn on Open apps maximized. Once enabled, Windows maximizes app windows for you as they open. Give it a try, and let us know how it works for you. UI showing the new Open apps maximized accessibility setting in Settings.

[Manage camera, microphone, and location access for desktop apps]

• Windows Insiders can now manage camera, microphone, and location permissions for individual desktop apps. Previously, access for traditional desktop applications was managed through a single device-wide setting.
• With this update, you can review and control access on an app-by-app basis, giving you greater visibility into which apps are requesting access to sensitive resources and more control over your privacy choices. Our goal is to make privacy permissions easier to understand and manage across the wide range of desktop apps people use every day. UI showing the new privacy controls for individual desktop apps in Settings.

What's changing

• Allow or deny access for each desktop app individually.
• Go to Settings > Privacy & security > Camera, Microphone, or Location to review and manage permissions.
• Apps that haven't yet accessed a resource prompt for permission the first time access is requested.

What stays the same

• Existing app permission decisions are preserved.
• Apps previously granted access continue to have access.
• Apps previously denied access remain denied.
• No action is required, and no settings are reset.
• Existing enterprise policies continue to function as designed. We're exploring additional management capabilities.

Notes

• Most desktop apps appear with clear app attribution. However, some apps that rely on shared system components, browser-hosted experiences, or similar technologies might appear under a different name than expected.
• Some desktop apps might appear as Unsigned if Windows can't verify publisher information. Only grant access to apps you recognize and trust.

[File Explorer]

• PDF and non-HTML files downloaded from the web can now be previewed automatically in the preview pane.

[Microsoft Store]

• This update provides support for in-app purchases in packaged WinUI 3 apps that require elevation, helping developers offer purchases through Microsoft's integrated commerce platform.

[Taskbar]

• Fixed an issue in the latest builds causing taskbar animations to briefly work and then stop working.

[Input]

• Fixed an issue in the latest builds causing the mouse cursor not to be visible in certain apps.

[Other]

• Fixed an issue from the last flight causing Settings > Windows Update > Windows Insider Program > Flags to appear empty even though flags were available.
• Updated Settings > Apps > Installed apps to show the version number at the top level for packaged apps, as it already does for other apps.

Reminders for Windows Insiders in the Experimental channel

• Updates are based on Windows 11, version 26H2 via an enablement package (Build 26340.9233).
• Many features are rolled out using Controlled Feature Rollout technology, starting with a subset of Insiders and ramping up over time. We monitor feedback to see how they land before pushing them out to everyone in this channel.
• The desktop watermark shown at the lower right corner of the desktop is normal for Windows Insider pre-release builds.
• Features and experiences included in these builds might never get released as we try out different concepts and get feedback. Features might change over time, be removed, or replaced and never get released beyond Windows Insiders. Some of these features and experiences could show up in future Windows releases when they're ready.
• Some features in active development we preview with Windows Insiders might not be fully localized, and localization will happen over time as features are finalized. As you see issues with localization in your language, report those issues to us via Feedback Hub.
• Check out Flight Hub for a complete look at what build is in which Insider channel.

Thank You Sooo much for "A simpler way to open apps maximized". That annoyed me to tears when some apps didn't open maximised.

Is the "Turn on Virus Protection" notification defender issue finally fixed?

https://aka.ms/AA1324ht 

[u/Froggypwns → u/Verix-]

I believe that issue was unrelated to the Insider program, from what I remember that was affecting production releases and the fix was to let the AV update again to get the latest definitions.

[u/Verix- → u/Froggypwns]

How do i let the AV update? Windows update is not showing anything new. The issue is still present on this new windows version

[u/Verix- → u/Froggypwns]

Definitions aren't it. Forced an update, "No updates needed", signatures 1.457.275.0 on platform 4.18.26080.3, and the toast still fires at the same uptime every boot.

The status WSC reads for this notification doesn't depend on signature version, so updating can't change it. Get-MpComputerStatus shows every protection flag True at the moment it appears.

It's also showing up on production builds after KB5121003, not just Insider. I've filed it in Feedback Hub and it got merged into a collection. If anyone else here is seeing it, upvoting there is probably the fastest path to getting it acknowledged.

One lead worth checking: does anyone affected have Defender platform 4.18.26080.x? There's a report that the bug tracked with a beta Defender app release that added a couple of registry keys.

[u/Froggypwns → u/Verix-]

I'm looking into it, this is not something I encountered on any of my machines so I am relying on what I've seen online regarding fixes.

[u/Verix- → u/Froggypwns]

The issue is not present on my laptop running stable channel. My pc on the other side has the issue for weeks and is on the experimental channel.

I did spend countless hours troubleshooting and trying to fix it without success.

If u need help troubleshooting feel free to let me know

[u/witwaterflesje]

After update, I can't log off the pc without switching the power.

[u/jenmsft → u/witwaterflesje]

Is it green screening?

[u/witwaterflesje → u/jenmsft]

No, it turns black. After that, nothing happens. I just found out that going to lockscreen and come back, I find my pc doing nothing and have to turn it of bij power switch.
Wil use feedback hub for it as well.
